Concept explainers
A bicycle has 25-in, wheels (in diameter).
a. What distance will the bicycle travel with one rotation of the wheels? Give the exact distance and an approximation to the nearest tenth of an inch.
b. How far will the bicycle travel with 200 rotations of the wheels? Give the exact distance and approximations to the nearest inch and nearest foot.
c. If the wheels turn at 80 rpm, what is the angular speed?
d. If the wheels turn at 80 rpm, what is the linear speed in inches per minute? Give the exact speed and an approximation to the nearest inch per minute.
e. If the wheels turn at 80 rpm, what is the linear speed in miles per hour? Round to the nearest mile per hour. (Hint:
